冷Isostatic press working principle：Uniform pressure is transferred through a liquid or gas medium, and the material contained in a sealed, elastic mold is pressed into a solid body, resulting in a body of original shape. The cold isostatic press uses liquid or gas as the pressure medium to pressurize the pressure medium through the hydraulic system or compressed gas system, so that it acts evenly on the pressed material, so as to achieve the density and pressing of the material. This compression method can generate pressures of up to several gigapascals, causing plastic deformation between powder particles to form a dense body. After the pressure is released, the mold is removed from the container, and after demolding, the body is further shaped and treated as needed.
